The increasing use of mobile applications in the retail industry has generated a large volume of user reviews that contain valuable insights regarding customer experience and service quality. However, the unstructured nature of these reviews requires an automated approach to extract meaningful patterns efficiently. This study aims to perform sentiment analysis on user reviews of the Indomaret Poinku application by integrating lexicon-based labeling with machine learning classification. A total of 10,000 reviews were collected from Google Play Store and processed through a series of text preprocessing steps, including cleaning, case folding, normalization, tokenization, stopword removal, and stemming. Sentiment labeling was performed using the Indonesian Sentiment Lexicon (InSet), producing three sentiment classes: positive, negative, and neutral. The labeled data were vectorized using CountVectorizer and classified using two algorithms: K-Nearest Neighbors (KNN) and Random Forest (RF). Evaluation results show that Random Forest outperforms KNN, achieving an accuracy of 82.5%, compared to 69% for KNN. Random Forest demonstrates superior performance in handling high-dimensional sparse text features and yields more stable predictions across sentiment classes. This study contributes to the growing body of research on Indonesian sentiment analysis by demonstrating the effectiveness of combining lexicon-based labeling with ensemble learning methods, offering practical implications for developers seeking to improve the quality and user satisfaction of digital retail applications.

The use of synthetic pesticides in the agricultural sector remains the primary choice for farmers in Indonesia due to their high effectiveness, but their massive use has negative impacts on human health and the environment. Therefore, there is a need for environmentally friendly and sustainable pesticide innovations. Red onion peel waste with the addition of TiO₂ nanotechnology is a strategic development step as a solution to the dangers of synthetic pesticides. Red onion peel contains bioactive compounds such as acetogenin, squamocin, gibberellin, cytokinin, and abscisic acid, which have the potential to be natural pest control agents. The process of making organic pesticides is carried out through the maceration of onion skins, followed by the addition of TiO₂ nanoparticles that act as photocatalytic catalysts to increase pesticide effectiveness and degrade synthetic pesticide residues. The development of these organic pesticides is in line with the principles of Green Chemistry, particularly designing safer chemicals, catalysis, design for degradation, and real-time pollution prevention. Through the implementation of strategic steps such as research, testing, socialization, and continuous evaluation, TiO₂ nanotechnology-based organic red onion peel pesticides have the potential to become a safe, effective, and environmentally friendly alternative in supporting sustainable agriculture in Indonesia.

The purpose of this study is to examine the effect of Good Corporate Governance (GCG), financial performance, and Earning Per Share (EPS) on firm value. The object of this research consists of state-owned enterprises (SOEs) listed on the Indonesia Stock Exchange during the period of 2021–2024. This study employs a quantitative approach using secondary data in the form of annual financial statements as the primary source. The sample was selected using purposive sampling based on predetermined criteria, ensuring that only companies with complete data and consistent reporting were included in the analysis. The independent variables analyzed include the audit committee, independent commissioners, institutional ownership, Return on Assets (ROA), and Earning Per Share (EPS). Multiple linear regression analysis was used to process the data in this study, allowing the researchers to examine the simultaneous and partial effects of the variables on firm value. The findings indicate that firm value is significantly influenced by financial performance, particularly ROA, highlighting the importance of operational efficiency and profitability in enhancing shareholder wealth. While certain GCG variables such as institutional ownership showed positive influence, other elements like audit committees and independent commissioners produced mixed results, suggesting that governance mechanisms may have varying effects depending on organizational context. Meanwhile, EPS demonstrated inconsistent results in relation to firm value, implying that market perceptions of earnings may not fully capture the impact on overall firm valuation. This study provides insights for policymakers, investors, and corporate managers on the relative importance of governance and financial indicators in value creation for state-owned enterprises.

Teacher professionalism is a key factor in improving the quality of education, especially in the context of rapid changes that demand continuous competency development. Therefore, sustainable professional development for teachers has become an essential need. This article aims to examine strategies for developing teacher professionalism through reflection and the implementation of best practices in learning.

Amidst the rapid development of digital technology today, copyright plays a complex role as an instrument for protecting works and at the same time as a potential inhibitor of innovation. Protection of exclusive rights granted by the copyright protection system aims to provide economic incentives or financial benefits to the creator. However, in practice, it often creates limitations on creative freedom, especially in the context of derivative works, remixes, parodies, and other creative uses that are developing rapidly in the digital realm. This study aims to examine how the copyright legal system, both normatively and implementatively, affects the scope of movement of creative actors in producing innovation. Through a normative legal approach with a review of international and national literature, this study found that copyright protection is too strict and has the effect of freezing reactivity, especially if it is not balanced with clear fair use provisions. However, on the other hand, loose regulations will also risk ignoring the moral and economic rights of the original creator. Thus, a balance is needed between the protection of individual rights and the public interest within the framework of a legal system that is adaptive and inclusive of digital culture. The study recommends strengthening open licensing frameworks such as Creative Commons, as well as updating national copyright policies to ensure that legal systems do not hinder, but rather encourage, the growth of innovation and creative expression in the digital age.

The development of transportation technology encourages companies to improve vehicle monitoring systems to be more effective and measurable, particularly in addressing speeding violations that can increase accident risks and reduce operational efficiency. This study aims to analyze the implementation and effectiveness of using a buzzer integrated with the Teltonika FMB910 GPS module as a vehicle speed warning indicator at PT. Lacak Cipta Aktual. This research employs a qualitative descriptive method with a case study approach, where data were collected through observation, interviews, and documentation during a one-month industrial internship and analyzed using the Miles and Huberman model, including data reduction, data presentation, and conclusion drawing. The results show that the system is capable of detecting overspeed conditions and automatically activating the buzzer when the vehicle speed exceeds the predefined threshold of 80 km/h. Based on logbook data, the system achieved a success rate of 93.9% in responding to overspeed conditions. The use of a buzzer is proven effective in providing immediate warnings to drivers, thereby improving driver awareness and speed control. However, the system still has limitations, particularly its dependence on GPS signal stability and vehicle electrical conditions. Overall, this study demonstrates that the integration of GPS and a buzzer provides a simple, effective, and cost-efficient solution to enhance driving safety and fleet management efficiency.

Bullying among adolescents is an aggressive behavior carried out intentionally, repeatedly, and involving an imbalance of power between the perpetrator and the victim. This phenomenon is an important issue because it can affect adolescents’ psychological well-being, social relationships, and academic achievement in both the short and long term. This study uses a literature review method by collecting and analyzing recent national and international studies regarding the causes, forms, and impacts of bullying. The findings indicate that bullying is influenced by internal factors, such as low empathy, poor self-control, negative self-concept, and the desire for social recognition. In addition, external factors also contribute, including parenting styles, peer influence, unfavorable school climate, and the development of social media that increases the risk of cyberbullying. The impacts of bullying are experienced not only by victims, who may suffer from low self-esteem, anxiety, depression, and social withdrawal, but also by perpetrators, who are at risk of developing persistent aggressive behavior and reduced empathy. Therefore, cooperation among families, schools, and communities is needed to prevent and address bullying effectively.

Micro, small, and medium enterprises (MSMEs) are crucial for driving regional economic expansion. Many MSMEs have not yet optimally utilized accounting data in selecting investments. This study aims to analyze the influence of accounting knowledge, entrepreneurial traits, and subjective norms on the use of accounting information in investment decision-making among MSMEs in Semarang City.
